Using the TechnoRiver Barcode Library with .NET applications

The TechnoRiver DLL transforms text characters into barcodes for your .NET projects using barcode fonts.

The steps for integration are as follows

1. Add the TechnoRiver DLL (TechnoRiverBarcodeFonts.dll) to your .NET project.

2. Use the namespace Net.BarcodeFonts.TechnoRiver to refer to the TechnoRiver Barcode Library.

For C#

using Net.BarcodeFonts.TechnoRiver;

VB.Net

Imports Net.BarcodeFonts.TechnoRiver

3. Create an instance of the TechnoRiverBarcodes class and adjusts its properties.

List of properties

BarcodeSymbology - the symbology to encode, for example, Code128 or EAN13

InputText - the data to be encoded.

ExtendedStyle - If ExtendedStyle is turned on, some bars will be longer than the rest. Barcodes that supports this property include ISBN13, ISBN, ISSN, EAN13, EAN8, UPCE, UPCA.

Non Extended	Extended

CheckDigit - if set to yes, will automatically append a check digit the barcode. The check digit is an extra digit or character used by the scanner to verify the data. For some barcodes, the check digit is mandatory, while for others the check digit is optional. This property is used by barcodes that check digits are optional . They include Code 39, Code 39 Extended, Industrial 2 of 5, I2of5, ITF14 and Modified Plessy.

For Example

TechnoRiverBarcodes acode = new TechnoRiverBarcodes();
acode.BarcodeSymbology = TechnoRiverBarcodes.BarcodeEnum.Code39;
acode.InputText = "1234567";
acode.CheckDigit = TechnoRiverBarcodes.YesNoEnum.Yes;

4. Invoke the generate() method to create the barcode

acode.generate();

5. Retrieve the output string with the EncodedOuput property. The EncodedOuput is the actual text that can be set with the appropriate barcode font and change into a barcode.

string encodedstr = acode.EncodedOuput;

6. Set the output string with the corresponding font. For example, if you are creating the Code39 Barcode, you will need to set the output string to the barcode font FontCode39H3 or FontCode39H3_TR (Trial font)

Font barcodefont = new Font("FontCode39H3_TR", 26);
textbox.Text = encodedstr;
textbox.Font = barcodefont;

7. Optionally retrieve the human readable text using the HumanText property. The human readable text is a text string that is usually drawn below the barcode to help people manually read the value in case the barcode cannot be processed by the scanner.

string humantext = acode.HumanText;

8. Optionally retrieve the EANText property if the barcode is ISSN, ISBN or ISBN13. These barcodes have an extra text string that is drawn above them.

Examples in C#

Examples of using TechnoRiver Barcode Library in a .NET 2 C# project.

using Net.BarcodeFonts.TechnoRiver;

//Code39 Example
TechnoRiverBarcodes acode = new TechnoRiverBarcodes();
acode.BarcodeSymbology = TechnoRiverBarcodes.BarcodeEnum.Code39;
acode.InputText = "1234567";
acode.CheckDigit = TechnoRiverBarcodes.YesNoEnum.Yes;
acode.generate();
string encodedstr = acode.EncodedOuput;

Font barcodefont = new Font("FontCode39H3_TR", 26);
textbox.Text = encodedstr;
textbox.Font = barcodefont;

//EAN13 Example
TechnoRiverBarcodes acode = new TechnoRiverBarcodes();
acode.BarcodeSymbology = TechnoRiverBarcodes.BarcodeEnum.EAN13;
acode.InputText = "12345678";
acode.ExtendedStyle = TechnoRiverBarcodes.YesNoEnum.Yes;
acode.generate();
string encodedstr = acode.EncodedOuput;

Font barcodefont = new Font("FontCodeEANEH3_TR", 26);
textbox.Text = encodedstr;
textbox.Font = barcodefont;

//Code128 Example
TechnoRiverBarcodes acode = new TechnoRiverBarcodes();
acode.BarcodeSymbology = TechnoRiverBarcodes.BarcodeEnum.Code128_Auto;
acode.InputText = "123456789";
acode.generate();
string encodedstr = acode.EncodedOuput;

Font barcodefont = new Font("FontCode128H3_TR", 26);
textbox.Text = encodedstr;
textbox.Font = barcodefont;

Note : The recommended size for the barcode font is 26, but it can be larger or smaller.

Note : textbox is a .NET TextBox with the properties Multiline set to True and WordWrap set to False

Example in VB.Net

Imports Net.BarcodeFonts.TechnoRiver

'EAN13 Barcode with no ExtendedStyle

Dim acode As TechnoRiverBarcodes
Dim encodedstr As String
Dim barcodefont As Font

acode = New TechnoRiverBarcodes()
acode.BarcodeSymbology = TechnoRiverBarcodes.BarcodeEnum.EAN_13
acode.InputText = "123456789"
acode.ExtendedStyle = TechnoRiverBarcodes.YesNoEnum.No
acode.generate()
encodedstr = acode.EncodedOuput

barcodefont = New Font("FontCodeEANH3", 26)
TextBox1.Font = barcodefont
TextBox1.Text = encodedstr

Note : The recommended size for the barcode font is 26, but it can be larger or smaller.

Note : textbox is a .NET TextBox with the properties Multiline set to True and WordWrap set to False
